BEND, OR -- A Bend man is under arrest for assaulting his ex-girlfriend with bear spray.

Investigators say the woman entered her Tumalo home, at about noon Friday, to find 34-year-old Chad Marcus inside without permission. He allegedly sprayed her and made threatening statements before running from the house, leaving the spray and a collapsible police-style baton behind.

The victim’s roommate called 911 and she was decontaminated by medics. Bear Spray is a type of pepper spray that can affect humans by causing temporary blindness, facial swelling and burning eyes and lungs.

Police immediately set up a perimeter and searched for the suspect, but they determined he had already left the area. A Deschutes County Deputy later talked with Marcus by phone and he agreed to turn himself in. He was booked at the Deschutes County Jail at about 4:30 p.m., Friday, on Menacing, Assault and Unlawful Use of Pepper Spray charges.
